I have an external hard drive attached to my wifi router in order to share files between 2 computers (I use it like a server). It had been working fine for several months, but last week something changed so that Finder is reading the wrong date/time modified for files on the external drive - all the dates are off by 1 day and 21 hours. For example, a file that I edited yesterday on my PC and copied to the external drive shows up in Windows Explorer as last modified yesterday when I view it on the PC. When I look at the same file in Finder on my Mac, it shows as modified tomorrow.
This is causing a problem because when I am moving some files, it will appear to me that a file I just edited on the Mac is older than a file I edited yesterday on the PC - so I'll work on the wrong version... Any thoughts on why this is happening or how to fix it. As I mentioned, it was working fine for months until last week. Thanks.
